Hyaluronic acid was historically extracted from rooster combs, an animal source, but most of what is sold today is produced by bacterial fermentation, which is vegan. The label form, sodium hyaluronate, does not reveal the route, so vegan status depends on the source. It is gluten-free. A supplier declaration confirms fermentation versus animal extraction.
What it means for each mark
- VeganCompatible when fermentation-derived, which most cosmetic grades are; rooster-comb hyaluronic acid is an animal product.
- Cruelty-FreeCruelty-free certifies no animal testing, a separate question from whether the hyaluronic acid is fermented or animal-extracted.
Where it typically hides
- Serums, moisturizers and sheet masks
- Injectable dermal fillers
- Joint-health and beauty supplements
- Eye drops and lubricating drops
- Wound-care and post-procedure products
What a certification review asks for
- A source declaration distinguishing bacterial fermentation from rooster-comb extraction
- The INCI or supplement specification for the hyaluronic acid grade
- Non-GMO documentation for the fermentation feedstock where a non-GMO claim is made
Alternatives
- Fermentation-derived sodium hyaluronate
- Plant polysaccharides such as tremella mushroom extract
- Glycerin and other humectants for moisture
Frequently asked questions
Is hyaluronic acid vegan?
Usually, but not always. Most hyaluronic acid today is made by bacterial fermentation, which is vegan. Some is still extracted from rooster combs, which is an animal source. A supplier declaration confirms the route.
How is vegan hyaluronic acid made?
By fermenting sugar with bacteria, which produce hyaluronic acid without any animal material. Brands using this route generally describe their hyaluronic acid as fermentation-derived or plant-based.
